SPECIFICATION forming part of Letters Patent No. 793,321, dated June 27, 1905.

Application filed August 31,1904. Serial No. 222,856.

To all who! if 'IIH/ l/ concern/.-

Be it known that l, Josnr ltuxxmsa resident of I'I( henrain, near llattling, Bavaria, (rermany, have invented certain new and useful improvements in Bottle-Qtoppers, of which the following is a specification, reference being made to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

My invention relates to improvements in stoppers for bottles designed to be filled and sealed under pressure and which because of the gaseous properties of their contents are closed by means adapted to resist internal [)l'QSSUl'Q.

My invention relates more particularly to stoppers which are adapted, in combination with ren'iovable corks or the like, to be seated on the mouths and secured to the necks of bottles by suitable clamping means.

One object of my invention is the provision of a stopper having a bore extending throughout its length and so formed as to receive a cork adapted to resist internal pressure by frictional contact with the stopper, which contact alone is sufficient to prevent the cork from being unseated. By means of this construction a great saving of expense is effected in the packing of bottled goods of this nature, inasmuch as it is unnecessary to rely upon sealing means for holding the cork in place. In the use of seals or like means the same are usually destroyed when once removed and are not serviceable for reseating the cork when only a portion of the contents of the bottle has been used. l'leretofore clamping means have been employed for holding corks in place; but this still further increases the cost of putting up bottled goods of this nature.

in my improved construction I provide a stopper for the bottle adapted to receive a removable cork and also serving by its peculiar construction to protect said cork from excessive pressure, said cork being held in place solely by frictional engagement with the stopper, thereby entirely avoiding the necessity of employ ing other clamping or sealing means.

My invention will be more fully described ings and will be more particularly pointed out 1 in the appended claims.

In the drawings, Figure 1 is a sectional view of the upper or neck end of a bottle, showing my improved stopper seated thereon with the cork in place. Fig. 2. is a plan view of parts shown in Fig. l with the cork removed.

Like characters of reference designate similar parts throughout the different figures of the drawings.

My invention consists generally of a stop per provided with a main body portion l), adapted to be seated and clamped upon the mouth of a bottle 1/. The stopper is preferably provided with packing composed of any suitable resilient material, permitting an air-tight connection of the stopper with the bottle. As herein shown, the stopper is removably secured to the bottle by means of a wire gripping device, consisting of downwardly-projecting loops 1* secured to the stopper and engaging a bail (.5, embracing a bead (1' upon the bottle-neck 1/. Said bail c is held in a gripping position and is tightly clamped beneath the bead a by a grippinglever (L2. The loop a, as shown, is pivotally secured to the stopper by being extended through an aperture formed in a laterallyin connection with the accompanying drawsection is desirably looped over a similar wing I). Said wing 11 is slightly recessed to prevent the loop 1 from slipping out of posil tion when the lever 1/ occupies a retracted position. It will be noted that while I have shown the stopper secured by this particular device I do not wish to be limited to the use thereof, as the said stopper would be equally serviceable if secured by other means. Said l stopper is provided with a bore extending throughout its depth and which is of relatively increased size at the upper portion of said stopper, as indicated at 1/. An annular recess (1 is also provided in cases where it is desired to display advertising matter, the said recess being enlarged to increase the area upon which the advertising matter may be disclosed. The upper portion of the bore 1 projecting wing b while the forward loop,

is of sufficient size to receive a cork (P or like plug and is desirably provided with annular ridges (Z adapted to impinge against the periphery of the cork to more securely hold the same in place. In order to prevent internal pressure of the bottle from engaging the cork throughout its lower surface and to thereby prevent the cork from becoming unseate-d should internal pressure in the bottle increase, the said bore is desirably reduced, as shown at c. In order to form a suitable seat for the cork when the same is forced into an extreme downward position, the reduction of the bore from the diameter shown at (Z to that indicated by c is abruptly formed, thereby securing a flat surface at (Z upon which the lower end of the cork is adapted to seat.

It will be obvious by reference to Fig. 1 that internal pressure on the cork is directed against such a restricted area thereof that the same will not be unseated or blown out even when the internal pressure is relatively high. By means of this construction no auxiliary clamping devices or sealing means are necessary, although sealing-caps may be used for purposes of display. It will be noted that if a large-sized cork is used having an extensive peripheral engaging surface the reduced portion of the bore 0 will not have to be restricted to such an extent as to impede the free outflow of the contents of the bottle.

It will not only be seen that a great saving is effected in the first expense of bottling goods equipped withstoppers of this nature, but that said stoppers are very convenient, for the reason that the user may draw off a portion of the liquid and quickly and effectively seal the bottle without fear of the cork being blown out or unseated.

WVhile I have herein shown and described a specific embodiment of my invention, I do not wish to be limited to the precise form shown, as it will be obvious that the same may be materially altered without departing from the spirit of my invention.

Therefore what I claim, and desire to secure by Letters Patent, is

1. A stopper provided with a bore of relatively reduced size in its lower portion and of relatively increased size in its upper portion, a cork or the like adapted for insertion in the larger portion of the bore, the same having annular ribs or like irregular surfaces engaging said cork to hold the same in place, a flat seat for said cork being formed at the point of reduction of said bore, the reduced portion of the bore protecting said cork from excessive pressure.

2. A stopper provided with a bore of relatively reduced size in its lower portion and of relatively increased size in its upper portion, a cork or the like adapted for insertion in the larger portion of the bore, the same having annular ribs or the like for holding the cork in place, the lower or reduced portion of the bore protecting said cork from excessive pressure.

3. A stopper provided with a bore of relatively reduced size in its lower portion and of relatively increased size in its upper portion, a cork or the like adapted for insertion in the larger portion of the bore, a flat seat for said cork being formed at the point of reduction of said bore, the reduced portion of the bore protecting said cork from excessive pressure.

4. A stopper provided with a bore of relatively reduced size in its lower portion and of relatively increased size in its upper portion, and a cork or the like adapted for insertion at the larger portion of the bore.

In testimony whereof I affix my signature in presence of two Witnesses.
